A Rare Presentation of Non-Hodgkin’s Lymphoma Presenting With Bleeding Esophageal Varices Secondary to a Malignant Portal Vein Tumor Thrombosis

A 60-year-old woman presented with six months of abdominal pain, weight loss and diarrhea for which she underwent bidirectional endoscopies that were unremarkable. Over the next two weeks, she developed non-cirrhotic portal hypertension and presented with esophageal variceal bleeding. A diffuse large B-cell lymphoma encircling her celiac axis with a tumor thrombosis of the superior mesenteric, splenic and portal veins was found to be the cause of her portal hypertension. An esophagogastroduodenoscopy (EGD) was performed to control her variceal bleeding. She was started on R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone) chemotherapy and after three cycles her symptoms have subsided, and a CT scan has shown shrinking mesenteric lymphadenopathy.
